Patented Oct. 20, 19 31 ITED STATES ADOLPH PO'I'DEVIN, OF GARDEN CITY, NEW YORK, ASSIGNOR TO POTDEVIN MACHINE COMPANY, OF BROOKLYN, NEW YORK, A CORPORATION OF NEW YORK ras'rme MEGHANISM Application filed February fl, 1930. Serial No. 428,885.

This invention relates to machines wherem a paste or adhesive pad receives the paste from a paste roll and applies it to material passing through amachine, and has for one of its objects the provision of means for returmng surplus paste to thev paste contamer.

In general my improved machine comprises a paste-applying pad rolling in contact with a paste roller, the pad applying paste to the paper or other material being operated on, a driven roller being located in proximity to the paste-applying pad and rotating in contact with the paste roller, whereby surplus paste thrown from the pasting pad is deposited upon this extra roller and removed therefrom by the paste roller and returned by it to the paste container.

In the drawings: Fig. 1 is an end view of a machine embodying my invention;

Fig. 2 is a view similar to Fig. 1 but with the parts in difierent'position; and

Fig. 3 is a plan view, partly in section, of 2 the apparatus of Fig.1.

Referring to the drawings in detail: 1 designates a paste fountain orcontainer, the expression paste being employed in a broad sense to include not only paste as such but any adhesive material.

Mounted within the fountain or container ,1 is a paste roller 2 adjustably mounted on a shaft 3 so that the periphery thereof may 'be adjusted with respect to the edge 4 of the 35' cut-out in the end of the container thereby to regulate the amount of paste carried on the face of the paste roller 2.

5 designates a shaft carrying a segmental pasting pad 6 which is adapted intermittently 4 to roll in contact with the periphery of the paste roller 2 to receive a coating of paste and to apply the same to paper or other material 7 advancing over a roller 8.

Above the paste roller 2 and pasting pad 6 is a paste collecting roller 9 mounted on a shaft 10. I

The shafts 3 and 5 are provided with intermeshing gears 11 and 12, while the shaft 10 carries a gear 13; intermediate gear 14 meshing with the gears 11 and. 13. This provides a drive for the paste roller 2, pasting pad 6 and paste collecting roller 9, the adjacent faces of paste roller 2 and paste pad 6 moving in the same direction, while the face of collecting roller 9 which is adjacent to and practically in contact with the face of paste roller 2 moves in the opposite direction to the face of the paste roller,

It will be appreciated from the foregoing operation that the paste picked up by the paste roller 2 is transferred to the face of the pasting pad 6, and the rotation of this pad into contact with the paper or other material 7 will apply a coating of adhesive to this material. It has been found in practice, however, that during the movement of the pasting pad 6, some of the paste is thrown from the face thereof and to prevent this paste being wasted or deposited on the machine I have provided the collecting roller 9, which is so placed as to receive this paste as I have at-' tempted to indicate in Fig. 2.

Inasmuch as the adjacent faces of collecting roller 9 and the paste roller 2 are rotating in opposite directions nearly in contact with each other it will be appreciated that any paste deposited upon the surface or face of the roller 9 from the pad 6 will be wiped therefrom by the paste roller and returned by it to the paste fountain 1.

What I claim is 1. In combination a paste roller, a paste pad, a paste collecting roller adapted to receive paste from said pad, said collecting roller being so disposed relatively to the paste roller that the latter will remove the paste therefrom. I

2. In combination a paste fountain, a paste roller mounted therein, a paste pad adapted to receive paste from said roller, a collecting roller adapted to receive paste from said pad, said collecting roller being disposed adjacent to the face of said paste roller whereby the paste deposited on the collecting roller will be removed therefrom by the paste roller and returned to said fountain.

- 3. In combination a paste fountain, a paste roller mounted thereimpaste applying means adapted to receive paste from said paste roller, a collecting roller so arranged with re- 100 spect to said paste applying means as to rethe collecting roller will he returned to the ceive paste therefrom during movement of the paste applying means, means for mounting said collecting roller adjacent the paste roller, and means for driving the adjacent faces of the paste roller and collecting roller in opposite directions whereby the paste on the collecting roller will be removed-therefrom by the fountain.

4. In combination a paste fountain, a paste roller mounted therein, paste ;apply1ng' means, means for regulating the amount of paste deposited by the paste roller upon the paste applying means, a collecting roller adapted to receive paste thrown from the face of the paste applying means, and means for mounting the collecting roller adjacent the paste roller and to drive the adjacent faces of these two rollers in opposite directions so that the paste deposited on the face of the collecting roller will be removed therefrom and returned to the fountain by the paste roller.

- 5. In combination a paste fountain, a paste roller mounted therein, a paste applying pad mounted "so as to receive paste from said paste roller, a collecting roller mounted in positionto receive paste thrown from the face of said pad, the adjacent faces of the Q paste roller and collecting rollermoving in opposite directions whereby the paste deposited onfthe collecting roller will be repaste roller and returned to the I fountain.

moved therefrom bythe paste roller and returned by it to said fountain.

6. In combination a paste fountain, a paste roller mounted therein, paste applying means mounted for rotation adjacent thepaste roller so. as to receive paste therefrom, a collecting roller mounted above said paste roller and paste applying means and in posi:

tion to receive paste from the paste applya ing means, the face of said collecting roller being adjacent the face of the paste roller, and means for driving said rollers in the same direction whereby the adjacent faces will be moved in opposite directions to ef fect removal by the paste roller of the paste de osited on the face of the collecting roller.

In combination a paste fountain, a paste roller adjustably mounted therein, paste applying means mounted adjacent the paste ro ler and in position to receive paste therefrom, a collecting roller mounted above the paste applying means and the paste roller and in position to receive pastethrown from the face of said paste applying means, means for driving the paste roller and collecting roller in the same direction so that'the adjacent faces will be travelling in opposite directions, said paste roller being driven in direcillODuWlth respect to said fountain whereby the paste removed thereby from the face of ADOLPH POTDEVIN.
